How is tapioca extracted from cassava ?

Cassava - common name for any of several related plants native to tropical regions in the Americas. Cassava is the West Indian name; manioc, or mandioc, is the Brazilian name; and juca, or yucca, is used in other parts of South America. The plant grows in a bushy form, up to 2.4 m (8 ft) tall, with greenish-yellow flowers. The roots are up to 8 cm (3 in) thick and 91 cm (36 in) long. The roots contain from 20 to 32% of starch at maturity. Early maturing cultivars are ready for harvest after 8-12 month. How is tapioca extracted from cassava? The question is now popular in Africa countries, and we are professional in the manufacturing the tapioca starch processing machine for many years, of course we are able to provide you the answer of the extraction process.

Tapioca extraction process

With the research of how is tapioca extracted from cassava, mounts of starch processing factories emerged worldwide. The starch produced from the cassava plant, which on account of its low content of no carbohydrate constituents might well be called a starch, is known in world trade as tapioca flour. It is used directly, made into a group of baked or gelatinized products or manufactured into glucose, dextrin and other products. Starch products are used in many food and nonfood industries and as chemical raw materials for many other purposes, as in plastics and the tanning of leather. Nonfood use of starches - such as coating, sizing and adhesives - accounts for about 75 percent of the output of the commercial starch industry.

The process requirements of how is tapioca extracted from cassava:

1. Make sure the freshness of cassava raw materials, so that the product quality and recovery rate can be ensured.

2. Completely remove the skin is necessary, because cyanide toxin is mainly concentrated in the cortex of cassava, and it can reduce the content of cyanide greatly.

3. In the process of how is tapioca extracted from cassava, the water consumption is large, and the processing water is required to meet the drinking standard.

4. Do not use iron equipment and pipes, because cyanide will be combined with blue iron cyanide to make starch coloring, so as to affect the quality of starch. The whole process of starch making is basically slightly acidic, so the material of equipment and fittings must be stainless steel. It is the main point in the process of how is tapioca extracted from cassava.

5. The volume of material transportation is large, so more pumps are needed. All kinds of pumps not only play a transport role, but also require a certain pressure to power the materials to achieve separation when the equipment is rotating at high speed.

6. Because the starch is easy to precipitate, the fiber is an uneven material, so the pipe elbow and other parts should have flanges or live joints. Once the blockage is convenient for disassembly and cleaning.

7. In order to ensure the quality of products, we should pay attention to cleaning equipment and sites frequently in order to keep them clean and sanitary.

8. Due to the acidity of starch, all slurry tanks should be treated with antiseptic treatment.

Along with the maturity of the process of how is tapioca extracted from cassava, the potential for Nigeria’s starch market is huge, as Nigeria is the largest cassava growing country in the world, with an estimated annual output of 45m tons, which continues to grow annually.
